In this study, 1,603 college athletes were participated and completed in three stages. The first study (n=378) was to develop a questionnaire manuscript and examine items analysis, factor structure and internal consistency. The second study (n=393) used confirm factor analysis to confirm the factor structure and examine criterion-related validity, convergent validity, discriminant validity, composite reliability and average variance extracted. The third study with 832 participants was to examine the measurement equivalence. Results showed that the newly developed 22-item sport motivation scale indicated with 6 factors, including intrinsic motivation, integrated regulation, identified regulation, interjected regulation, external regulation and a motivation. Further, we adopted recent literature and combined integrated regulation and identified regulation into a new dimension entitled ＂autonomous extrinsic motivation＂ as second-order factor; and combined external regulation and interjected regulation into a new dimension entitled ＂controlled extrinsic motivation＂ as another second-order factor. Through the alternative model comparisons, the measurement equivalence indicated that our scale provides good reliability and validity. We concluded that our sport motivation scale has proved to be suitable for assessing the athlete motivation.","PeriodicalId":338279,"journal":{"name":"Sports & Exercise Research","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122121310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to explore the core thoughts, feelings and expectations of athletes throughout the course of an overseas competition. Therefore, narrative inquiry methods and the Zaltman Metaphor Elicitation Technique (ZMET) were employed to identify the key constructs formulated in the athletes' minds and to create a consensus map. The results indicated that 43 key constructs were identified, including 10 originator constructs, 25 connector constructs and 8 destination constructs. The final values comprised professional attitude, athletic goals, training concepts, coach behavior, ties of affection, cultural confusion, self-learning, and self-reflection. This study concluded that athletes produced their experiences, combining the 2 abilities of determination and action to sustain selfexploration during the sporting event journey. The dynamic process of self-integration involving the 3 elements of consciousness, activation, and reflection was a learning continuum of learning-by-doing, thinking-by-learning, and changing-by-thinking. Finally, it is suggested that the findings derived from this study verify that the consensus map created through the ZMET can be used as a reference for designing the athletic training programs, marketing strategies for cities sponsoring major events, and government policies.","PeriodicalId":338279,"journal":{"name":"Sports & Exercise Research","volume":"213 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121634851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to investigate the types of nutritional supplements, information sources and reasons to intake the supplement by players. Survey data were collected from 233 triathletes (157 Sprint, 57 Olympic and 19 Elite), who participated in 2013 Ilan Plum Blossom Lake Triathlon Competition. Our data showed that 35.2% of the participants having more than NT$ 50,000 income per month. Among the different types of supplements, sport drink was the most commonly consumed nutritional supplements. The rate of energy bar consumed by elites was lower than that in Sprint or rest of the groups during competition. The consumption of powder and capsules in Sprint was lower compared to the other groups. The major reasons for nutritional supplements intake were to provide the enough nutrition, reduce fatigue and improve performance. Elite group had higher demand rate of increasing energy and less fatigue compared to other groups. Sprint group had lower demand rate of performance improvement, training effect improvement and increasing immune function compared to other groups. The information sources for nutritional supplements intake were mainly from friends (57.9%), advertisement (31.3%), coach/trainer (26.2%) and peer (24.9%) for all athletes. In particular to groups, 78.9% from coach/trainer in elite group; and 56.1% and 66.7% from friends in Sprint and Olympic groups respectively. These results provide information for triathletes-related practitioners and nutritional supplement supplier.","PeriodicalId":338279,"journal":{"name":"Sports & Exercise Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131501638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eight elite male swimmers and eight club level college male swimmers participated in the study. Two underwater high-speed cameras (200Hz) were set in the transverse and sagittal plane under the water and synchronized to capture one cycle of butterfly stroke movement. The kinematics data were digitized and calculated with the Kwon 3D software. The continuous relative phase was calculated using the normalized time series of the angular displacement and angular velocity of the shoulder and knee joints angles. Macroscopically, one cycle of the arm-leg coordination pattern can be observed between two levels at three race paces in butterfly stroke: a consistent relationship (2:1) exists between two dolphin kicks and one arm stroke in butterfly swimming. The continuous relative phase analyses showed that, in the beginning of the stroke-catch phase, the continuous relative phase was from anti-phase (-180°) to in-phase (50°). For the pull phase, the in-phase relation (±50°) remained unchanged throughout the stage. During the push phase, the relative phase gradually increased toward anti-phase (180°). The percentage of catch, pull, push, and recovery phases were not evenly distributed across one cycle of the butterfly stroke. Especially in elite group, there is a trend of decreasing the percentage of catch phase. In conclusion, these results provide useful information for swimmers as well as coaches to examine the swimming movement of the butterfly stroke.","PeriodicalId":338279,"journal":{"name":"Sports & Exercise Research","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123755174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies found that increasing contextual interference (ICI) practice and faded feedback (FF) are the learning variables. However, beneficial effect of combining these two variables on motor learning is still unclear. Thus, this study was designed to examine the additive effect for motor learning by combining the increasing contextual interference practice with faded feedback. Forty adults were randomly assigned into four groups: Random-all feedback, random-FF, ICI-all feedback, and ICI-FF groups. Sequential relative timing movement was utilized as an experimental task. One hundred and eight trails were performed in the acquisition phase. Twenty four hours later, twelve trails in the retention test were completed. The obtained results were as follows: (1) AE (absolute error) was significantly different in blocks during acquisition phase. (2) For retention test, AE and E (total variability) were not significantly different between the group combined ICI practice with all feedback and the group combined ICI with FF. Furthermore, AE of groups combined FF and all feedback with ICI practice were found to be significantly lower than that of groups combined FF and all feedback with random practice. In conclusion, no additive effect for motor learning was found when combined increasing contextual interference practice with faded feedback.","PeriodicalId":338279,"journal":{"name":"Sports & Exercise Research","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129041461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a counterbalanced, cross-over design study, 12 female weightlifters were asked to intake 4 different rehydration solutions after they lost 2% body weight through acute dehydration in sauna. The 4 types of rehydration solutions were hypoosmolar electrolyte solution (HES), iso-osmolar electrolyte solution (IES), sport beverage (SB), and water (W). The intake amount of rehydration solution was 1.5-fold to the lost of their body weight due to dehydration. Each rehydration solution was ingested immediately after dehydration, 30-min, 60-min, and 90-min of rehydration. The gastro intestinal comfort score and body weight were recorded during the rehydration period. Blood samples from each participant were collected to determine the levels of osmolarity, glucose, sodium, potassium and chloride before dehydration and during rehydration period. Wingate anaerobic test was also performed before dehydration and at 120-min of rehydration. The results indicated that gastro intestinal comfort score of the participants in HES, IES and SB supplements were significantly lower than in W supplementation at 90-min of rehydration. The blood glucose levels in subjects with HES, IES and SB treatments were significantly higher than in W treatment at 60-min. The blood potassium level in subjects with HES treatment was significantly higher than in SB and W treatments at 120-min. However, there were no significant differences on the anaerobic power and fluid retention percentage among the supplements. The major conclusion of this study is that supplementation of 4 different rehydration fluids after acute dehydration had no effects on the anaerobic power. Nevertheless, intake of the rehydration fluids containing carbohydrates and electrolytes resulted in superior scores of gastro intestinal comfort, and could maintain higher blood glucose and electrolyte concentrations.","PeriodicalId":338279,"journal":{"name":"Sports & Exercise Research","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133173981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All participants performed two experimental trials: flat-water slalom race (FS) and white-water slalom race (WS). The two experimental trials were separated by a 7-day interval. Heart rate (HR) was measured throughout the trials, and capillary blood samples were collected before and after the race for lactate analysis. In the results, significant correlations were found between the performances of WS and FS trials, and also between WS performance and the coefficients of variation in WS/FS trials. Race speed in FS trial was significantly faster than that in WS trial. However, there were no significant differences in HR_(peak) and blood lactate concentrations before and after the race in both experimental trials.

Twenty-four healthy middle-aged women were participated, and equally assigned into either the concurrent circuit exercise group (CCEG) or the control group (CONG). The concurrent circuit exercise is a combination of both aerobic and hydraulic resistance exercise. Subjects in CCEG performed a concurrent circuit exercise 3 times per week for 12 weeks. The exercise program was composed of 20-30 min main exercise that maintained the intensity at 60-80% HR_(max) of subject's heart rate, and 6-min stretching exercise. Subjects in CONG did not participate in any exercise program during the experimental period. The body weight, body fat percentage, waist-to-hip ratio, and blood pressure of all subjects were assessed before and after 12-week exercise program. Fasting blood samples were collected to determine the level of blood glucose, triglyceride (TG), total cholesterol and high-density lipoprotein cholesterol. The low-density lipoprotein cholesterol and atherosclerosis index (AI) were calculated. The results indicated that CCEG subjects showed significantly lower diastolic blood pressure, blood glucose, TG and AI values after 12-week exercise. However, such beneficial effect was not observed in CONG subjects at the end of the experiment. Moreover, average diastolic blood pressure of subjects in CCEG was significantly lower than CONG subjects. This study concludes that 12-week concurrent circuit exercise program could effectively lower the blood pressure, fasting blood glucose, TG, and AI, which are the risk factors for metabolic syndrome in women.","PeriodicalId":338279,"journal":{"name":"Sports & Exercise Research","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127030709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
